* Remove __metaclass__ = type.
for i in $(grep -REl '__metaclass__ = type' plugins/ tests/); do
sed -e '/^__metaclass__ = type/d' -i $i;
done
* Remove super arguments, and stop inheriting from object.
* Make all doc fragments, module utils, and plugin utils private.
* Remove some unused and no longer needed imports.
This hopefully also fixes the CI issues, which do not happen locally for me...
* Fix formatting.
* Try to make CI happy, again.
* Fix imports.
* Lint.
* Remove unicode text prefixes.
* Replace str.format() uses with f-strings.
* Replace % with f-strings, and do some cleanup.
* Fix wrong variable.
* Avoid unnecessary string conversion.
* Don't assume that docker version/info JSON output contains the expected fields.
* Allow CLI modules to not require the API version.
* Add changelog fragment.
* Add note on idempotency.
* Make platform a list of strings.
* Support specifying secrets.
* Add test for secrets.
* Support specifying outputs.
* Ignore invalid choices syntax for ansible-core <= 2.16.
It actually works with ansible-core 2.14+ (though not with <= 2.13),
but the sanity tests only accept it from 2.17 on.
* Only use --secret with type=env for buildx 0.6.0+, and multiple --output for buildx 0.13.0+.
